SPECIFICATION formingpart of Letters Patent No. 666,618, dated January22, 1901.

Application filed May 29, 1899. Serial No. 718,780. (No modelshowing therelative positions of the contact- To ail whom it may concern:

Be it known that 1, CHARLES D. WRIGHT, a citizen of the United States,residing at Ohicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Electric Igniters, ofwhich the following is a specification.

This invention relates to improvements in devices to be employed forigniting gases, and while i't-is more especially intended to be used inconnection with stoves in which gas or gasolene is used as fuel, yet itmay be employed for igniting gases used for other purposes; and itconsists in certain peculiarities of the construction, novelarrangement, and operation of the various parts thereof, as will behereinafter more fully set forth and specifically claimed.

One object of my invention is to provide a simple and inexpensiveigniter for gas and other ignitable substances which shall be of such aconstruction and nature that an electric spark may be produced at thedesired time and point, thus dispensing with the use of matches ortapers, the unburned portions of which are frequently thrown aside whilestill burning and often cause accidental tires and explosions.

Another object of myinvention is to so construct the handpiece of theigniter that it will not become short-circuited when laid upon ametallic surface.

Still another object of my invention is to so construct it that it maybe readily attached to the supply-pipe of the stove in such a positionthat it will be entirely out of the way and yet always accessible.

In order to enable others skilled in the art to which my inventionpertains to make and use the same, I will now proceed to describe it,referring to the accompanying drawings, in which Figure 1 is aperspective view of a gasstove with my igniter attached thereto. Fig. 2is a perspective view of the handpiece of the igniter, showing by dottedlines the position which a portion thereof will assume when the sparkshall have been produced. Fig. 3 is a central sectional view of thebattery and coil casing; and Fig. 4 is a side or detached view of aportion of the handpiece,

ing points.

Similar letters refer to like parts throughout the different views ofthe drawings.

A represents the casing for the battery- 'cells B and B and sparkingcoil 0, which casing is preferably tubular, as shown in the drawings,and may be provided with clamps a to encircle the gas or gasolene supplypipe A of the stove. Secured to one end of the casing A is a metal cap Awhich has a central projection a to rest against one end of the cont-actpost b of the battery B, the other end of which post rests against thead jacent end of the post- Z) of the battery B, the other end of thepost Z) of the battery 8 resting against the adjacent end of the post 0of the sparking coil 0, the other end of said sparking-coil post restingagainst a plate d, insulated from the metal cap A secured on the otherend of the casing.

Passing through the cap A and insulated therefrom is a conductor I), oneend of which contacts with the plate d, and the other end thereof issecured to the hand piece E, as shown in Fig. 2 of the drawings.Connected at one of its ends to the cap A is another conductorD, whoseother end is electrically connected to a metal spring 6, which issecured to one end of the handpiece E and insulated therefrom. (See Fig.2.)

The hand piece E is made of a piece of wire bent back upon itself toform a spring and having near one of its ends a U-shaped loop E for thereception and operation of the other end of the handpiece, which isprovided with a piece 6, preferably in the form of a spiral spring, tocontact with the arm e of the handpiece, which arm projects crosswise ofthe loop E, but at some distance therefrom, as is clearly shown in Figs.2 and 4 of the drawings. The arm 6 is of sufficient length and so bentas to prevent it and the piece e contacting at the same time with themetal surface, such as the top of the stove, on which the handpiece maybe placed, thus preventing short-circuiting, which would occur if apiece of metal united the piece (2 and the arm 6 or other portion of thehandpiece.

From the foregoing and by reference to the drawings it will be seen andclearly understood that by pressing the portions of the hand piecetoward each other, so that the piece 6 will contact with the arm a, aspark Will be produced, the conductor D being connected to one of thepoles of the batteries, While the conductor D, through the metallic capsA A and casing A, is connected to the other pole.

It is apparent that the batteries must be insulated from the casing, andthis may be done by providing the interior of the casing or the exteriorof the batteries with suitable insulating material, or they may beinsulated in any other desired manner.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In an electric igniter, a handpiece comprising a continuous piecebent to form a with a yielding contact-point, substantially 30 asdescribed. v

CHARLES D. WRIGHT.
